1.	Calculate wavelength of radiation emitted when electron de exists from n=2 to n=1 hydrogen atom
Answer» The observed hydrogen-spectrum WAVELENGTHS can be calculated USING the following formula: 1λ=R(1n2f−1n2i) 1 λ = R ( 1 N f 2 − 1 n i 2 ) , where λ is the wavelength of the emitted EM radiation and R is the Rydberg constant, DETERMINED by the experiment to be R = 1.097 × 107 / m (or m−1).
